Hi,

Applications like juk and amarok (so far, it seems they are  the only 2 affected here) crash at startup.


Error message:
juk(19872): Communication problem with  "juk" , it probably crashed.
Error message was:  "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" "

KCrash: Application 'juk' crashing...
sock_file=/home/kde4/.kdemod/socket-cghislai/kdeinit4__0



backtrace: 
Application: JuK (juk), signal SIGILL

It seems related to Phonon, somehow; but since ive found this error message used to happen on startup of several kde4 applications, id like to think its a more general thing.

Anyway, i contacted the guys providing the binaries (kdemod.ath.cx/) and they updated it to recent SVN :

$ kded4 -v
Qt: 4.4.0
KDE: 4.00.82 (KDE 4.0.82 >= 20080610)
KDE Daemon: $Id: kded.cpp 813532 2008-05-27 23:21:49Z dfaure $

The first binaries i tried used the qt phonon; the second one use kde phonon. I tried both phonon backends but the same error come back.

I tried compiling DBUS from git as there was a somewhat recent fix about timer (http://gitweb.freedesktop.org/?p=dbus/dbus.git;a=commit;h=cdca6dbce88fd1e1195e2a81eb6619c782df2fac), it didnt work.

Restarting DBUS, rebooting, cleaning .kde & co don't work.

I'd be glad to help further, but i still have some exams to pass :D

Thanks,

Charly
